Chapter 697 (1/2)

The key to the method of dividing pills is stripping. Similar to chemical refining, you can add a herb with opposite properties at will, and use the principle of mutual generation and elimination of drugs to urge the Dragon alchemy formula to peel off the pills layer by layer.

The highest level of separating pills is to completely separate all the drugs in pills. It is as difficult as refining advanced pills.

But what Zhang Yitian needs is only ten thousand year ginseng King grass. If the other attribute drugs in the pill are destroyed, it's no big deal. Therefore, the difficulty of separation is relatively weak.

Wannian ginseng is positive, so it needs to add negative drugs to separate. Before picking medicine in snake Valley, Zhang Yitian collected many herbs with extremely negative attributes, which are just in use now. I took a herb, took off its leaves and threw it into the Dan stove. Suddenly, a strange fragrance came out.

Tianxiang herb is a very special herb. Nun loves it, because this herb can be used to refine Ningxiang pill. After taking it, the body will emit a faint fragrance, which smells very good. In addition, Tianxiang herb is also an essential herb for refining aphrodisiacs, which can increase interest.

However, Zhang Yitian didn't want to refine Ningxiang pill or aphrodisiac. Just because this herb is negative, which is just opposite to the drug properties of Wannian Shenwang pill, it is the most suitable introduction for separating pills, so he grabbed it at random.

The separation process of pills is slow, so we need to be careful, otherwise it will cause the situation of furnace explosion, destroy the pills, and even kill the alchemist.

Smelling the faint aroma of Tianxiang grass, Zhang Yitian was in high spirits, carefully controlled the Dan fire and kept heating the Dan furnace.

Generally, alchemists will face the unstable situation of Dan fire, but Zhang Yitian knows the divine dragon alchemy formula. With the assistance of Dan formula, the temperature fluctuation of Dan fire is very small, the calcination is uniform, and the control is more convenient.

Under such preconditions, the separation work progressed rapidly. The Danlu gradually turned red, and the fragrance of Tianxiang grass decreased. Then a faint fragrance of medicine floated out, which was the aroma of Shenwang grass, which also showed that Shenwang grass had been gradually extracted.

The first wisp of medicine fragrance wafts out, indicating that the method of dividing pills is progressing smoothly. Next, as long as this state is maintained, the ginseng King grass will be completely refined.

As time went by, the fragrance of the medicine became stronger and stronger. At one moment, the fragrance of Tianxiang grass completely disappeared. Zhang Yitian slowly took back the Dan fire, sat cross legged and waited for the heat of the Dan stove to dissipate.

After a while, the red color on the furnace completely disappeared. Zhang Yitian got up, opened the furnace cover, looked at the bottom of the furnace, and saw some white powder precipitated at the bottom of the furnace.

”It's successful!” Zhang Yitian was delighted. He reached out and twisted a pinch of medicine powder, rubbed it between his fingers, then took it under his nose and smelled it. He was surprised and said to himself, ”unexpectedly, the method of dividing pills can also improve the purity of medicine powder.”

Compared with before, the amount of powder extracted at this time is much reduced, but the purity is much higher, reaching an extreme state.

With successful experience, Zhang Yitian was confident, and then tried again and again. The success rate of separation reached 100%, which strengthened his confidence. However, he did not immediately separate Shenwang pill, but took a nourishing pill to continue the experiment.

Just now I was doing experiments with spirit liquid. Facts have proved that there is a great difference between liquid medicine liquid and solid Dan medicine. Before, the success rate of Zhang Yitian's extraction of medicine liquid reached 100%. It can be replaced with Dan medicine. The first one failed. The main reason is that the Dan medicine is not easy to absorb natural fragrance herbal medicine liquid.

Put tianxiangcao into the pill oven and melt into liquid instantly. These liquids can only adhere to the surface of the pill. It is very difficult to penetrate into the pill, resulting in the conflict between the properties of the pill and the final destruction of the pill.

Zhang Yitian suffered a lot when he failed. At the same time, he was still terrified. If he had separated Shen Wang Dan directly just now, Shen Wang Dan must have destroyed one. You know, there are only two pills and only two opportunities. If he failed, he would delay too much time.

After sitting in situ for a moment and repeatedly studying the separation method recorded in the Dragon alchemy formula for several times, Zhang Yitian finally found the problem. The Dragon alchemy formula has a complete set of processes, including eight steps: Pharmacy, Qingding, wending, medicine, refining, Zhending, Chengdan and Wendan.

One of them is called ”Zhen Ding”. At first, Zhang Yitian thought that when the pill was about to be completed, the Ding furnace would vibrate, but he realized it was his own mistake. The so-called shaking tripod really means to use the palm technique to shock the tripod furnace. Its purpose is to break the pill.

When the pill becomes a powder, it can better integrate with the separated liquid medicine, and there will be no problem faced by Zhang Yitian just now.

After finding the root of the problem, the depression suppressed in Zhang Yitian's heart dissipated.

Clean up the residue in the pill oven. Zhang Yitian picked up a nourishing pill, threw it into the pill oven, and then put in a plant of tianvanilla. The herb was roasted by the pill fire and turned into liquid medicine. Then Zhang Yitian raised his palm and hit it on the pill oven in the air. The pill oven cheered up and turned the nourishing pill into powder.
